A rigorous blockade being maintained, the British army began to suffer considerably for fresh meat and vegetables. The small parties which sailed from Boston, in quest of these articles, were frequently disappointed by the vigilance of the minute men. But the continuance of active exertion, which this service required on the part of the inhabitants of the sea coast, soon became burdensome; and the governors of the several colonies pressed for detachments from the main army. Although it was impossible to spare the troops required, without hazarding the cause of the colonies, great irritation was excited by the refusal to comply with these demands of particular protection. They at length became so importunate, and the unavoidable refusal to comply with them was so ill received, that congress was induced to pass a resolution, declaring that the army before Boston was designed only to oppose the enemy at that place, and ought not to be weakened by detachments for the security of other parts of the country. At Newport, in Rhode Island, the committee sought to secure the place, by entering into a compromise with Captain Wallace, who commanded the ships of war on that station, stipulating that he should be furnished with provisions on condition of his sparing the town, and committing no depredations on the country. This compromise contravened so essentially the general plan of distressing the British forces, that General Washington deemed it necessary to interpose, and represent to the Governor of that province, the mischief to be apprehended from so dangerous a practice. While the blockade of Boston was thus perseveringly maintained, other events of considerable importance took place elsewhere. In July, Georgia joined her sister colonies, and chose delegates to represent her in congress: after which, the style of "The thirteen United Colonies" was assumed; and by that title, the English Provinces, confederated and in arms, were thenceforward designated. {September 5.} After a recess of one month, congress again assembled at Philadelphia. The state of the colonies, and the letters of the Commander-in-chief being immediately taken into consideration, the scarcity of arms and ammunition engaged their most serious attention. Great exertions[14] had been made, by importation and by domestic manufacture, to extricate the country from this perilous situation; but the supplies were unequal to the necessities of the army; and the danger resulting from the want of articles, so vitally essential in war, still continued to be great. [Footnote 14: The agents of congress had the address to purchase all the powder on the coast of Africa, and that within the British forts, without attracting notice; and to seize the magazine in the island of Bermuda. Great exertions were also made in the interior to obtain saltpetre and sulphur, for the manufacture of that important article.]
